| <- audio-connection [pack~] | [drip] | [exp] <- this is the ctrl-obj. you want to have as an audio-obj. | [repack 64] <- 64 is the blocksize | [unpack~] | <- audio-connection
i'm not sure, but i think this solution is more cpu-intensive than a 'real' [exp~]. be aware of that.
wow ... do this too often and your cpu power will be gone ... i would try something like that with a table lookup ... should be faster (no benchmark, just my feeling)
cheers ... tim
